| Abstract: | By analyzing the actual situation that Tunlan mine has the occurrence of gas, in the Southern fourth panel 12403 the working face using coal seam reticulated boreholes and predrainaging methane resolve gas emission of the working seam. After the application, it has better effect and a promotional value for management of mining coal seam gas emission. |
